Now that Marilyn: The Musical has an investor in Nick Jonas' Lyle West, the musical, I presume, can really kick into high gear. There are three songs that will be featured in tonight's episode, "Let's Be Bad." Megan Hilty will perform the title song, "Let's Be Bad," an original. Katharine McPhee will take on the James Brown classic hit, "It's a Man's Man's Man's World." And Will Chase will cover Donny Hathaway's "A Song for You," which is a fantastic song, if I do say so myself.
